Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a bed device used for purposes such as medical treatment, and particularly to a technique for simply and hygienically disposing of excrement after defecation.

[Conventional technology]

As a type of bed device used for medical treatment of bedridden elderly and sick people, a toilet opening window is formed on a mat attached to a mat stand, and a toilet bowl is placed directly below the toilet opening window when using the toilet. Some devices are designed to allow a patient to relieve themselves while lying down.

In this type of bed device, when disposing of excrement after defecating, the accompanying person must replace the toilet bowl each time, or store the excrement discharged in the toilet bowl in a container or bag. It was customary to use methods such as throwing it away later.

Furthermore, in large facilities, when installing this bed device, a method has been proposed in which a communication pipe is provided to communicate the toilet bowl and the sewer pipe, and the excrement is discharged through this pipe. Or was used.

[Problem that the invention attempts to solve]

However, when using the above-mentioned bed device in a general household, etc., if you want to install a communication pipe that connects the toilet bowl and the sewer pipe, you have to drill a hole in the floorboard or bury the pipe in the soil. This requires large-scale piping work, which is uneconomical, and it also becomes impossible to easily change the installation position of the bed equipment once it has been installed, resulting in indoor layout problems and installation space problems. will occur.

On the other hand, when an attendant disposes of excreta as described above, all the work must be done manually, which of course makes the disposal extremely troublesome and complicated. This may lead to problems from a sanitary standpoint, such as getting the hands of the person dirty or creating a bad odor in the room.

[Means for solving problems]

In view of the above circumstances, this invention was developed by adding a new configuration to a bed device that allows for urination while lying down, thereby eliminating the need for large-scale plumbing work, and making it possible to dispose of excrement easily and hygienically. This was done as a technical problem to provide a bed device that can perform the above-mentioned bed, and the means for this purpose are: a mat stand disposed on the upper part of the base; a mat attached to the mat stand; A bed device having a toilet opening window formed in the mat and configured such that the toilet bowl is positioned directly below the toilet opening window when using the bed, the bed device being rotatably held on the base. a rotary table; a bag placed on the rotary table with an open top end; and a rotary drive for rotating the rotary table so that the bag is positioned directly below the outlet of the toilet bowl when using the toilet. and an adhesive device that adheres the upper end of the bag after urination by operating a pair of pressing plates that approach each other and move away from each other.

[Effect]

According to the above means, when the rotary drive device is activated by a switch operation or the like when using the toilet, the rotary table on which the bag is placed rotates by the required angle, and as a result, the bag is moved to the outlet of the toilet bowl. Rotate to a predetermined position below.

Under these conditions, if a patient sleeping on a mat defecates through the opening for the toilet, the excreta will fall or flow down from the toilet bowl's outlet and pass through the opening at the top of the bag. and is housed inside the bag. After using the bag, a pair of pressing plates (for example, a pair of heating plates) in the bonding device approach each other and press the upper end of the bag. As a result, the upper end of the bag is bonded (eg, bonded by heat), and the bag is sealed.

In this case, if a plurality of bags are placed on the rotary table at equal angular intervals, that is, at the required angular intervals, the series of operations described above can be performed continuously.

In addition, the actuator such as a motor that operates the above-mentioned adhesive device is as described in the following examples.
It can also be used as an actuator of a rotary drive device that drives a rotary table.

A one-way clutch 35 is interposed between the actuator 39 and the rotation support shaft 34, which is locked when the actuator 39 rotates in the forward direction and unlocked when the actuator 39 rotates in the reverse direction.
When 1 and 41 adhere the bag body 33, the rotary table 30 is held in a stopped state, and when the pair of press plates 41 and 41 are separated, the rotary table 30 is rotated at 45 degrees along with this operation. only rotates.

When the patient uses the toilet again, the pair of pressing plates 41 and 41 after the bag body 33 is attached
As the rotary table 30 has already rotated by 45 degrees due to the phase-separation movement of The bag 33 is stored inside a new bag 33, and after using the toilet, the upper end of the bag 33 is adhered by the pressing plates 41, 41, so that the bag 33 is completely sealed.

Note that this embodiment uses a single actuator 39.
is used to rotate the rotary table 30 and move the press plates 41, 41 toward and away from each other. However, this invention is not limited to this, and the rotation of the rotary table 30 described above is not limited to this. A configuration may be adopted in which the driving and the operation of the pressing plates 41, 41 are performed using separate actuators.

Furthermore, the bonding device 40 in this embodiment has the following properties:
Although the upper end of the bag 33 is configured to be thermally bonded, other methods may be used, such as attaching adhesive or adhesive tape to the inner peripheral surface of the upper end of the bag.
A method may also be used in which the region is pressed against the surface using a pressure plate.

[Effect of idea]

As described above, according to this invention, a bed device that can be used while lying down is equipped with a rotary table on which a bag whose top end is opened is placed, and when the bag is used, the bag is placed at the outlet of the toilet bowl. In addition to driving the rotary table so that it is placed directly below, the system also includes an adhesive device that automatically adheres the upper end of the bag containing excrement, making it easy to connect the toilet bowl to the sewer pipe. This eliminates the need for extensive piping work, making it possible to easily change the installation location of bed equipment.
Layout and installation space problems are solved, and excrement is disposed of quickly and automatically, making it easier to handle waste than in the past, when all work was done manually. Work can be carried out in a sanitary manner, and furthermore, the burden or annoyance imposed on the worker is effectively reduced.
